Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1 and Figure 5, including shell, optical module are installed in the shell of sealing, and one is also equipped in shell
First fan 3 and heat sink assembly 9, the outside of shell are equipped with second fan 8, and the second fan 8 passes out inside
The heat come dissipates, and the first fan 3 drives the flowing of enclosure interior air-flow, and the front end of shell is provided with optical module, optical module
Output end install a lens assembly 15.Heat sink assembly 9 luxuriant and rich with fragrance mirror 11, heat-protecting glass 12, liquid crystal display 13, preceding phenanthrene after being installed on
The side of 1 air outlet of mirror.
Wherein, optical module includes a light cone 10, rear luxuriant and rich with fragrance mirror 11, heat-protecting glass 12, liquid crystal display 13, preceding luxuriant and rich with fragrance mirror 14 and one
Reflective mirror 2, rear phenanthrene mirror 11, heat-protecting glass 12, liquid crystal display 13, preceding luxuriant and rich with fragrance mirror 14 are successively installed on the side of light cone 10, light source assembly 7
